IMPROVEMENT IN TWISTING AND'SPINNING HEADS.

Specification forming part of Letters Patent No. 115,435,dated May 30, 1871.

Toell whom it may concern."

Be it known that'I, JOHN W. OHAPPELL,

, of Berlin, in the county of Ottawa and State of Michigan, have invented a new and Improved Spinning-Head; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a 1 part of this specification.

My invention consists incertain combinations of mechanical devices, as hereinafter 1 fully described and subsequently pointed out 5 in the claim, for removing and twisting slivers from the cardingmachines and depositing y them upon rollers or bobbins.

My primary object is to enable those skilled in the art to which this invention belongs to dispense with condensers and jacks, and to thereby simplify and cheapen manufactured yarn. to the public. 1

gitudinal section of my spinning-head. Fig. 2 is an end view, showing a front detail View. Fig.3 is a side view of acarding-cylinder with my improved spin.-

, hing-head arranged at a tangent thereto, and showing the relative position of the winding and tension spool. I

A, Fig.1, represents a hollow cylinder. B Bare rolls, having a worm on the peripheries and oblique teeth on one edge of each. These teeth on the two rollers point obliquely in opposite directions. 0 is a worm-spindle arranged between these rollers to rotate them,

and, pointed at the end to center in the axis of cylinder A. D is a tube passingthrough the latter cylinder, and having head E, with leather wiper F, in front of rollers B B. It

j is rotated by power appliedat the other end for the purpose of operating said wiper. H, Fig. 3, is a cardingcylinder, andJ is a spoolonwhich the yarn is wound asfast as twisted.

K is a drum, which, in connection with the 1 spool, affords the necessary tension to the yarn as delivered from the spinning-head. L represents the driving'shaft of the spinning-head, while a a. b 1) 0'0 are differential spur-gears, which impart a more rapid motion to the wipertube D and the worm-cylinder 0 than to the cylinder A.

. The mode of operation 'is as follows: As 7 the carding-cylinder carries the fiber around on its circumference the said fiber is brought into contact with the oblique teeth on the edges of rollers B B. Separate slivers are removed by each set of teeth, and, as they are being carried around by them, are brushed off by the wipers F at a point opposite to tube D. Through this tube they pass in one continuous yarn, which has been twisted between the; point of delivery and the tube. From this tube the twisted yarn passes directly to the spool J Having thus described all that is necessary to a full understanding of my invention, what I esteem as new, and desire to protect by Letters Patent, is-

1. In combination-with a carding-cylinder, H, the above-described. spinning-head and spool mechanism, operating substantially as and for the purpose specified.

2. In spinningheads, the rolls B B, slowly revolving in opposite directions on their own axes, and rotated, at the same time, in a plane at right angles to their axes, and having the.

reversely-obliqued teeth on the edges thereof, all substantially as and for the purpose specifled.

3. The tube Dhaving wiper F, and rolls B B having reversely-obliqued teeth on their edges, combined and operated together, as and for the purpose specified.
